XCMG Crawler Crane Track Roller Assembly - Photo Reference
This page shows a track roller assembly photo reference for an XCMG crawler crane undercarriage. A track roller supports the lower track run and guides it through its flange profile. Correct selection depends on the machine configuration, roller geometry and mounting interface, not on colour or general appearance.
Functions to Confirm
The roller carries repeated contact load from the track links while helping keep the chain aligned. Its tread width, flange arrangement, overall length and bracket connection must correspond to the crawler frame and track group. A mismatch can affect side clearance, contact distribution and installation.
Identification Checklist
Complete XCMG crane model and serial number
Original part number or readable casting and stamped marks
Single- or double-flange profile and clear end-view photographs
Tread diameter, tread width and overall roller length
Mounting-hole spacing, bracket width and bolt size
Photos of the installed position and adjacent track links
Wear and Leakage Observations
Inspect the tread for uneven wear, deep fluting, flat spots or impact damage. Check flange faces for one-sided contact that may indicate alignment or track-chain issues. Oil traces, looseness or abnormal noise can point to a seal or internal bearing problem, but the cause should be evaluated with the surrounding undercarriage rather than diagnosed from one photograph.
Fitment Verification
Take dimensions from clean, unworn reference surfaces and compare both ends of the removed roller. A crane model family may use different mounting brackets or roller sizes, so the serial number and measurements remain important. We do not publish unverified load ratings, seal types or cross-model interchangeability.
Packing and Storage
Finished tread, flange and mounting surfaces should be protected from corrosion and hard impact. Rollers are dense and can move inside weak cartons, so export packing should restrain each unit with separation between metal surfaces. Packages are labelled by confirmed reference and quantity for receiving checks.
Frequently Asked Questions
How do I distinguish similar track rollers?
Compare the flange profile, tread and overall dimensions, mounting-hole spacing, bracket width, markings and machine serial number.
Should other undercarriage parts be inspected?
Yes. Track links, shoes, idlers and sprockets can influence roller wear and alignment.
Can a roller with no readable label still be identified?
Often it can be narrowed down using machine data, multiple-angle photos and accurate measurements, followed by buyer confirmation.
